homemade smoke machine

can be used to detect leaks in intake, exhaust, tranny, rear diff, etc.

you might be able to make one with a wet/dry vacuum, some dry ice and water, and a home made regulator. 1.) connect the vacuum hose and regulator to the vacuum on the exhaust side. 2.) put the water with the dry in a the vacuum 3.) turn on the vacuum and let the fun begin.

you could actually put a restriction on the intake side of the vacuum too.

you could also rent a party smoke machine but i don't know if this smoke would hurt the car

Fog Juice Recipe
WARNING: THERE HAS BEEN SOME CONCERN ABOUT THE CORRECT MIXTURE OF MATERIALS TO MAKE FOG JUICE. SINCE FOG JUICE IS READILY AVAILABLE, YOU MIGHT CONSIDER PURCHASING IT FROM A REPUTABLE SOURCE INSTEAD OF MAKING YOUR OWN IF YOU ARE CONCERNED ABOUT THE MIXTURE AND CHEMICALS USED.

WARNING: USING HOMEMADE FOG JUICE IN A COMMERCIAL FOG MACHINE COULD VOID THE WARRANTY.

ALSO: COMMERCIAL FOG JUICE IS FAIRLY INEXPENSIVE ($4 - $6 per quart at Fred Meyers and Walmart) NOW AND HAS BEEN REPORTED TO PRODUCE BETTER FOG.

You can make your own fog juice from glycerin, diethylene glycol, dipropylene glycol, propylene glycol, or triethylene glycol and distilled water. Glycerin is available at drug stores, supercenters, and home-brew stores. The others are available from chemical supply companies.

Glycerine Based Fog
You want to use the lowest ratio of glycerin to water that acheives fog for health reasons. Generally, your fog juice will be between 15% to 30% glycerin and 70% to 85% distilled water. A common lean ratio for light fog is 1 part glycerin to 8 parts distilled water. The lean recipe would then be to mix 4 ounces of glycerin in 1 quart of distilled water or 125 ml of glycerin in 1 liter of distilled water. A common rich ratio for heavy fog is 1 part glycerin to 4 parts distilled water. The rich recipe would then be to mix 8 ounces of glycerin in 1 quart of distilled water or 250 ml of glycerin in 1 liter of distilled water. When vaporized, the vapor should have a somewhat sweet smell. If it smells burnt or fowl, then the ratio of glycerin to water is too high or the temperature of the fog machine is too high.

Materials (English Units)
4 ounces Food Grade or other High Purity Glycerin ($4.00 from drug store)
1 quart (32 ounces) Distilled Water ($0.25 from grocery store)
Materials (Metric Units)
125 milliliters Glycerin
1 liter Distilled Water
Instructions
Mix the glycerin into the distilled water. Stir will. Use twice as much glycerin if you desire thick fog, but some experimentation will be necessary. If you use the leaner glycerin recipe, it will be cheaper, and and the fog will be cleaner though the fog will be lighter and not last as long.

 

Great!

 

It would hurt the car? what car?

I don't get it?

 

what people think of...lol....

 

why????????

 

Cause it makes you shift mad quick yo!

 

I dont know why people are making fun of this. This sounds like a good DIY way to locate vaccume leaks. This is mighty handy tool on the FD with all the lines and people that cant pinpoint where the leak is coming from.

 

they will figure it out eventually. i swear you try to be helpful and all you get is negative bs.

 

I actually have an evap system leakdown tester at my work that does this. I never really paid attention to what is used for the smoke but its very useful in diagnosing small leaks. I never used it on my FD and now that my rats nest is out i dont plan on it.

 

 

or you could just use big blue(we use it in the hvac industry) ><

 

what is big blue?

 

It's a very good idea, I've heard of something like this being used by dealerships to diagnose vacuum leaks. I think everyone is giving you a hard time because they think you're doing it for a "cool" effect.

 

you could also use something to regulate the speed of the vacuum motor. i actually just thought of it because we were trying to figure out why another forum member's car wouldn't stay running below 4000 rpm.

 

Don't sweat it. Most are just noobs who spend 90% of their free time in the Lounge increasing their post count and the remaining 10% on **** sites decreasing their eye sight.

 

You say that like it's wrong or something.

 

I have a smoke machine.... a car.... and a leak in my oil system. I think im going to drain the oil hook up the ol' smoke machine and give it a try. I was looking for a good way to pinpoint the leaks i have to give you props for the idea i hope it'll work!

 

thanks! i just thought of how to make a homemade smoke machine with a vacuum cleaner someone else thought of using smoke to detect a leak along time ago.

 

I didnt get what you wer using it for maybe ill read things a little more thorough next time, anyways i have used a shop vac blower to find a boost leak so i cant really talk, lol

That was me i think.
